Jiao Li was one of the teachers in the CELTA course I was a tutor. This is a Cambridge Assessment 120-hour training program for English teachers.
The course was run on an online basis and included live, assessed teaching practice sessions in addition to language awareness and teaching methodology workshops.
Jiao was a diligent trainee teacher and was eager to develop professionally and made good progress in the course. His written assignments were of high standard.
He also has a very pleasant classroom manner and is able to build good rapport with his students. He is adept at motivating and encouraging the learners through good quality presentations and visual
support. He prepared a variety of off-the-shelf and teacher-generated activities and tasks to meet his lesson objectives, and was supportive and helpful when monitoring the students.

Jiao' excellent command of the English language and background in academia make him an excellent choice as a teacher, especially for those with EAP needs. His assignments on our course were of an exceptionally high standard and his eye for detail and passion for language shine through in his work.

Jiao is an outstanding tutor! His fluency in both Mandarin and English makes him an excellent choice for anyone looking to improve their language skills. He explains things clearly, tailors lessons to your level, and makes learning enjoyable and effective.

A patient, encouraging and detail-oriented teacher who really helped me get a start with Mandarin Chinese. I would recommend to anyone starting out.

I observed six hours of Jiao teaching English to pre-intermediate and advanced students, and can say that he is a very patient, kind teacher who is deeply invested in his students’ success.

Additionally, as someone who himself learned English to a very advanced level, he has a strong technical understanding of English grammar, and can pre-anticipate learners’ mistakes.

I highly recommend Jiao as a teacher because he is a committed and a passionate educator. I met him during a teacher training course which held on 2025. We were in the same group in the workshop. He has a clear voice, disciplined, and a responsible person. He strives to create a classroom that nurtures both learning and personal growth. Jiao is also a confident educator who is willing to engage in discussion and embrace challenges.
